RUDOLF LQEB, OF JENKINTOWN, PENNSYLVANIA.

OBNAMENTAL EMBROIDERY.

Specification of Letters Patent.

Patented July lid, 119M.

Application filed June 29, 1914.. Serial No. 848,022.

To all whom it may concern:

Be it known that I, RUDOLF Lone, a citizen of the United States, and a resident of J enkintown, Montgomery county, Pennsylvania, have invented certain Improvements in Ornamental Embroidery, of which the following is a specification.

My invention relates to ornamentation effected by embroidery stitching, and comprises a seam or other ornamental effect for sewed articles which is preferably circular in outline and with which I combine a novel ornamentation or effect in the form of a central knot or raised portion; the whole constituting a representation of large embroidered buttons or circular flower-like effects, simulating daisies and the like.

An important feature of my present i11- vention is the production of the raised center or knot in connection with the novel character of embroidery or embroidered seam forming the subject of my invention. Surrounding this raised center are a plural ity of rows of stitches which are substantially radial. The raised center may overlap the inner annular row of radial stitches, or a space of plain fabric may be left between this raised center and the innermost row of stitches. In addition the two sets of radial stitches overlap each other and the effect produced when threads of different colors are employed is highly ornamental.

My present invention comprises the improved embroidery or embroidered seam as a new article of manufacture, the process of making the same forming the subject of a separate application filed December 19, 1914, Serial No. 87 8,095.

These and other features of my invention will be more fully described hereinafter, reference being had to the accompanying drawings, in which:

Figure 1, is a view of the obverse side of one form of scam made in accordance with my invention, showing the means employed in laying the several sets of stitches;

Fig. 2, is a view of the reverse side of the seam shown in Fig. 1;

Fig. 3, is an enlarged sectional view on the line 3-8, Fig. 1, showing the needles and the rotating presser foot;

Fig. l, is a view illustrating a modified form of embroidered ornamentation within the scope of my invention;

Fig. 5, is a view of the reverse side of the embroidery shown in Fig. 4, and

Fig. 6, is a sectional view on the line 66, Fig. 3.

In the formation of the embroidery or embroidered seam forming the subject of my present invention, I employ a sewing ma chine with a plurality of vibrating needles 1, 2 and 3, which needles are set in line with each other and vibrate in a single plane coincident with the plane of their position, and such machine is equipped with mechanism in the shape of a rotating fabric moving device whereby the material operated upon may be turned with respect to a predetermined center while the needles are vibrating and laying the desired stitches; the rotative movement of the fabric with respect to the vibrating needles, while the latter are laying their stitches, being wholly under the control of the operator.

While the fabric material is being turned, the stitches from all three needles are laid in a radial direction with respect to the predetermined center, and this center will be at some point intermediate the throw of the end needle 3.

By this means, I am able to form a seam which is preferably circular, which consists of stitches 5 radiating from a common predetermined center and forming an outer annular row or series; stitches 6 radiating from the same center and set inwardly with respect to and directly adjacent the stitches 1; overlapping the same in fact, and a third set of stitches 7 which cross each other over the common predetermined center as the fabric is rotated and result in the formation of a central knot for the ornamental effect desired, which center is composed of stitches raised materially higher than either of the annular rows or sets of stitches, 5 and 6.

It will be understood, of course, that each needle will lay the same number of stitches, and by causing the stitches of one of the needles to cross the predetermined center of the object being formed, the height of such center will naturally be raised. The respective stitches 5, 6 and 7, showing on the face of the fabric have pairs of loops 5*, 6 and 7 disposed on the under side of the same, and these several pairs or sets of loops are caught by a single shuttle thread 8.

In the form of ornamentation shown in Figs. 1, 2 and 3, the inner raised eye or center is directly adjacent the inner ends of the intermediate set of stitches.

In the form of ornamentation shown in carrier 10 having a friction Figs. 4:, 5 and 6, the throw of the needles is i such that the inner raised center will be formed of stitches 7 entirelyindependently of the intermediate annular row of stitches 6, providing a blank space 9 in the fabric intermediate the raised center and said annular row of stitches6.

The effect of the ornan'ientation is materially heightened by employing threads of different colors for the respective sets or rows of stitches.

The fabric is moved by means ofa rotatable member such as shown, for instance, in my application for patent filed Dec. '31, 191-3, Serial No. 809,798, comprising a fixed member 11 rotatably mounted in said carrier with a ball bearing for the latter; the friction member engaging the fabric and turning with the latter when the operator moves the tambour frame in which the fabric is stretched. This 7 fabric moving device is adjustable so as to change the center of the same with respect to the throw of the needles and effect circular ornamentation of various sizes. The needles may also be set in different relations with respect to each other; changes in the throw of the shuttle being correspondingly effected.

In order to accommodate the raised center made by the stitches 7 during the formation of the same, the presser foot 12 is provided with an enlarged space 18 at the outer end. of the slotted portion accommodating the needles. This presser foot is employed solely to hold the fabric while the needles are in the same to insure proper coaction of the shuttle thread and is raised when the needles are raised; having no feeding or other moving effect upon the fabric which is wholly under the control of the operator.

I claim:

1. An embroidery seam as a new article of manufacture consisting of a piece of fabric having a plurality of independent annular rows of stitches formed by continuous needle threads radially disposed, said needle threads producing a figure having a plurality of substantially circular outlines with a raised central portion comprising a series of stitches crossing each other.

2. An embroidery seam as a new article of manufacture consisting of a piece of fabric having a plurality of independent annular rows of stitches concentrically disposed formed by continuous needle threads radially disposed, said needle threads producing a figure having a plurality of substantially circular outlines with a raised central portion formed by the inner annular row of stitches crossing each other.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
